Jumboframes and Veritas Cluster

We've got two Sunfire V480Rs configured in a Veritas cluster using VCS.
The sunfires are are
64 bit Sparc Solaris 9 and connected to a Storedge 6320 array via 2Gb
fibre channel. There are
two 2TB vxfs filesystems on the array. The patch level of VCS and VxFS
is 3.5MP2-RP2.

Each sun box has four gigabit n etwork interfaces; two ge interfaces
which are used for heartbeat
and two gigaswift intefaces which are connected to our production network.

We want to install jumbo frames on both machines, but don't want to
break the cluster in
the process.

Does anyone have this type of configuration or know that it's bad or
good to use jumboframes
in a cluster environment?

Thanks

Mark
